To all whom it may concern:

Be it known that we, V RNE G. KENNEDY and MILL RD B. KENNEDY, citizens of the United States, residing at Canton, in the county of Lincoln and State 0t South Dakota, have invented certain new and useful Improvements in Apparatus for lreating POl6S, Of which the following is a tionr 7 This invention relates to preserving appaspecificarat us, particularly to apparatus for treating wooden poles, such as telegraph poles, with preservatives, and has for its object the provision of a novel form of apparatus whereby poles may be treated with a preservative under pressure for only a short distance above and below the ground line.

An important object is the provision of an apparatus of this character in which the treatment takes place within an air-tight tank completely inclosing the entire poles.

A further object is the provision of such anapparatus so designed that the minimum amount of preservative maybe applied, thus reducing waste and also the expense.

Other objects and advantages, such as slinplicity in construction and operation, cheapness in manufacture, efficiency in service, and the general improvement of the art, will become apparent during the course of the 'following description taken in conjunction with the accompanying drawing, in which:

Figure 1 is a vertical longitudinal sectional view of the apparatusfand Fig. 2 is a cross-sectional view there through.

Referring more particularly to the drawing, the numeral 1. designates a tank, preferably cylindrical in shape and provided with an air-tight fitting cover 2 held in position by any suitable means, such as the clamps 3. Y i

Adapted is a partition plate 4 provided with any suitable or desired number of circular holes 5, through which the poles 6 are adapted to be passed. At each of the holes there are pivoted, as at 7, similar semicircular ring members 8 having their free ends outwardly turned at 9 and adapted to be held together b suitable clamp members 10. Packing rings or. strips 11 of felt or other suitable material are disposed between the poles 6 to be disposed within the tank 1 plate 4, the pressure below the pi and the clamping ring sections 8, forjform ing a tightoint about the poles.

"A pipe 12'Qcommunicates with the tank 1 at itsyupper end and is adapted to-supply air under pressure to the 1111561101 of the tank. A similar pipe 13 communicates with the lower portion of the tank, both of these pipes being provided with suitable valves 14 and 15. Anotheri pipe 16 communicates with the tank 1 at a considerable distance above the bottom thereof, and is provided with a cut-0H valve 17, this pipe being for the purpose of supplying the preservative into the tank; An :outlet pipe 18 provided with a valve 19 communicates with the tank 1 immediately above the plate dand leads back td the reservoir containing the liquid. At its extreme bottom the tank has communicating with its interior a drain pipe 20 having a valve 21,

The operation of the device is as follows: The cover 2 bein open, the poles 6 are low.-

cred into the tan 1 in any suitable manner and are passed through the ,holes 5. Access to the interior of the tank is had by means of a manhole 22 closed by a suitable door-23.

Through this manhole the operator then 15 are opened and compressed air-supplied to the tank above and below the partition plate 4. Inorder that the liquid may not leak down around-the poles .and around the ate 4 should e always greater than'that supplied to the tank above the late. The pressure above the partition willforce the preservative into the wood and will causethat. portion of the pole between the partition plate and the top of the preserving liquid to become impre t e at nated. After ogeration is comp e the liquid may be rawned through the A pipe 18 and returned to the reservoir for the next treatment. If by anychance any small amount of liquid might leak into the space below the plate 4, it maybe drained off through thepi'pe From the foregoing description together with a study of the drawing it will be ap parent that we have thus provided a simple and eflicient (device whereby poles of any length may be treated with preservingliquid of any kind for a desired distance intermediate their ends, and at any desired pressure, thus effecting a great savin in material .and still rendering the po es unsusceptible to moisture.

- Itwill be understood that We reserve the right to make such changes in the form,

construction and arrangement as will not de-.

* part from the spirit of the invention and which will be within the scope of the subjoined claims.

Having thus claim: I v 4 1. An apparatus for treating Wooden poles with a preservative comprising a tank,

described our invention, we

' a cover therefor forming an airtight recep ;,tac1e, apartition platedividingsaid tank into upper and lower compartments, said 'fplate being provided with holes, for the pas-' sage of poles to be treated, clamping mem berson said plate engagingt he po-les,,packi ing members between said clamping mem'-- bers and the poles; forming -Iiquid-tight .joints', a feed pipe discharging into, the upper compartment whereby a preservative I liquid niay be introduced to a desired ,depth upon said-partitlon plate, and a compressed j alr conductmg 'plpe. communicating with said upper compartment above said first named pipe, and a drain pipe communicating with ,said upper compartment adjacent said partition plate. I 7

2. An apparatus for treating wooden poles with a preservative, comprising a tank,

a partitionplate Within said tank provided with holes for the insertion therethrough of poles to betreated clamping members on said plate surrounding said holes and engaging the poles for holding them at selected heights above the bottom of the tank,

packing strips disposed between said clampmg members and said poles and forming liquid-tight joints, a pipe for supplying a' preservative'liquid into said tank above said partition plate, and a drain pipe.

3. An apparatus for treating wooden poles with a preservative, comprising an air tight tank, a partition plate therein dividing the of the tank, means; for supplying a preservative liquid within the upper compartment to a selected height above said partition plate, and ajeompressed air conducting pipe communicating with the upper compartment'j or applying pressure npon the preservative liquidftherein.

In testimony wthereof we heretoafliin our signatures VERNE Q, KENNEDY.
